Distance Weightage (IDW) in ArcGIS was used to find out overall rainfall variation in the study area Weighted Overlay Analysis is used for assigning weightage (%) and ranks to The hydrology tools focus on the movement of water across a surface. A pour point is the point at which water flows out of an area. 3.1.6. Advanced Raster Calculations: Map Algebra Map algebra is the analysis language for ArcGIS Spatial Analyst. Basic drainage parameters measured and analysed included stream order, stream length, stream pattern, flow direction, bifurcation ratio, drainage density, stream frequency and flow accumulation. Higher drainage density is associated with the basin of weak and impermeable subsurface material, sparse vegetation and high relief. Road Drainage: Where density, topography, soil and slopes permit, vegetated swales should be used in the street right-of-way to convey and treat stormwater runoff, replacing curb and gutter drainage systems. Sign in to your ArcGIS Online account. Drainage density (Dd) is a measure of total stream length of a basin to the total area of the basin (Strahler 1964 ). This results in a raster of drainage basins. Explore some of the DNR's most requested information in the Map section or search directly for spatial information in the Data section. quantities as weights in the flow accumulation to map channels with a drainage density that adapts to topographic variability. How to calculate density. Starting ArcMap, opening ArcCatalog, and adding data layers To start ArcMap, choose Start All Programs GIS Applications ArcGIS ArcMap 10.4.1 1. They derived a potential drainage density map using ARCGIS software and a drainage network map derived from a DEM (90 m resolution SRTM DEM). Lithology map Drainage A drainage basin is a natural unit draining runoff water to a common point. If the input features are points, then the distances will be measured using the geodesic method. Determine the area of the drainage basin(s). 1:16000 Soil Grid Field investigation and SOTER by FAO 1:16000 Land use/land cover mapping Grid Digital LULC map, Image classification tool in ArcGIS … This site provides information about the East Baton Rouge Parish GIS Program. Infiltration is a function of a number of interactive factors—lithology, lineament frequency density, karstification, and drainage density)—that can be manipulated using GIS. The second watershed has a drainage density of 1.23 km/km2 (area=20 sq. Topographical Map 1:25000 Slope, aspect and drainage density map Raster DoS map, Using Spatial Analyst Extension in Arc GIS 10 and Aster (DEM) data. Drainage density, defined as channel length per unit watershed area (km km-2), reveals the amount of channels in a watershed.Drainage densities in semi-arid to humid landscapes range from 2 to 12 km km-2, primarily reflecting variations in precipitation (Abrahams 1972) and lithology (Grant 1997) and see Eccker 1984 and Bloomfield et al. The results The drainage density map was prepared using the line density analysis tool in ArcGIS. This area is normally defined as the total area flowing to a given outlet, or pour point. They first assigned a value of one to each cell representing a drainage line. .Drainage map, drainage density map and slope map were prepared by analysing DEM. I want to use different techniques for representing drainage density like Kernel density for polyline features. I have generated grid using fishnet tool in Arc GIS over my study area. #----- # Name: Calculate Density.py # Description: Calculate density using the count of points as well as the severity # value of outbreaks by week. Creating a Map with ArcMap You will now learn the basics of using GIS data to explore an area and create a map. Explore DNR Maps: View one of our six featured maps (below) or view all Maps and Apps. The density of the water network depends on the size of the raster: ... a new vector file (point type) is created, the editing mode is activated and the exact outlet or drainage point is drawn on the water network of the basin to be delimited. In … km and total stream length=24.586743 km). My study area is subarnarekha river basin and i want to calculate drainage density for each grid (2km*2km). Elevation Analysis was undertaken in ArcGIS/Arcview environment. The drainage density map was created from the drainage network map generated from ASTER-DEM. 34 out of 85 towns. The accuracy of the drainage area calculation depends on the map scale, technique, demarcation of the drainage divides, among other reasons. The best results will be obtained if when the input D8 Flow Direction raster was created, the Force all edge cells to flow outward option ( FORCE in Python) was enabled. Such analysis can be integrated into morphometric analysis, crop suitability model, and the likes. The role of drainage density on soil loss has been established with multiplication of drainage density and soil loss map in raster calculator tool of ArcGIS. This story map was created with the Story Map Journal application in ArcGIS Online. A mathematical model for this system, which was developed by C. E. Jacob, can be expressed in the equation T= WD~2/8h0t in which T is transmissibility, W is recharge, D is drainage density, km and total stream length=34.436 km). Find. One watershed has a drainage density of 1.08 km/km2 (area=32 sq.

Further, the drainage density map was reclassified into three distinct classes, such as high (≥3 km km −2), moderate (1.6–3 km km −2), and low (≤1.5 km km −2) and indicates that the majority of the basin area (67%) belongs to moderate drainage density class. Drainage map was updated using toposheet. The Canada: Waterflow Map seen to the right shows the four largest watersheds in Canada. ... permeability and drainage class are the critical attributes determining the pathway water takes across the landscape and the strength of soil zone reduction, respectively. The apparently smoother surface in Missouri is an artifact of the lower data density in the map coverage from Missouri. In the MRB, drainage density ranges from 0 to 4.02 km km −2 . 3. Drainage network helps in delineation of watershed. Work with smart, data-driven styles and intuitive analysis tools. The map emphasizes the effect of the Pleistocene glaciations (see Map 3), which completely altered the drainage patterns in Illinois and Indiana. The flow of water through a drainage system is only a subset of what is commonly referred to as the hydrologic cycle, which also includes precipitation, evapotranspiration, and groundwater flow. Pour prévoir des valeurs en fonction de mesures de points, utilisez l'outil Interpoler les points. Density values are calculated using the algorithm from the Kernel Density tool in ArcGIS Pro. A listing of Frequently Asked Questions is available at the bottom of the page. Your efforts will be focused on India. Other common terms for a drainage basin are watershed, basin, catchment, or contributing area. I have calculated drainage density for two watershed and need to make sense of the numbers. The drainage density map was prepared using the Arc Hydro tool box (Ibrahim-Bathis and Ahmed 2016). This map was categorized into five classes using a quantile classification scheme (Figure 3(e)). Once the data has been gathered, the typical process for estimating the curve number for a drainage area is as follows: Define and map the boundaries of the drainage basin(s) for which curve number(s) will be calculated. 3.3.1 Preparation of slope and drainage density maps The slope tool in a spatial analyst toolbox of ArcGIS 10.4 was used to create the slope map from Cartosat-1 DEM. Limitations Density can be calculated for point and line features only. This functionality is part of the TauDEM software available from .
