Article outline
Main goal
– use of ArcGIS and Surfer for water reservoir volume calculation
Brief description of procedure:
- Data collection (GPS RTK survey and echosounding)
- Data processing (point-class data of surveying)
- Creation of the models (ArcMAP and Surfer)
- Use of models for water volume calculation
Introduction
Smal water reservoir (SWR) - STN 73 6824:
• Max. depth: 9m
• Max. volume 2×106 m3
• Max. Q100: 60 m3. s-1
In Slovakia approx. 200 SWR’s – mostly multifunctional (irrigation, flood protection, fish production)
Siltation – result of erosion – threat to all water reservoirs
Introduction
• Siltation - threat to all
water reservoirs
• Bottom morphology changes
• Storage capacity reduction
• Overall impact to environment

Equippment
GNSS receiver: Leica 1200+
Sonar: GPSmap 721s
Vessel: Raft boat proppeled wit electric engine
Data collection
Automatic non-contact bottom surveying - during the sail
GNSS RTK surveying (vessel position) - point each 2 m
Echosounding (depth measurement) – NMEA connection
Direct GNSS surveying - water level, dam, safety spillway
Data processing
Import of collected data to Leica GeoOffice
Calculation of the x, y, z S-JTSK coordinates in MS Excel
Data processing
Reduction of input points – distribution in 10 x 10 m grid
Data processing
Adding of shoreline bottom points and islands terrain points
Shoreline bottom elevation:
Water level – 0,35 m
Island terrain elevation:
Water level + 0,75 m
DEM creation - ArcMAP
Created models:
• Topo to Raster (2×2 m cell size, interpolation executed with “Enforce with Sink” option)
• Spline with Tension (2×2 m cell size, tension weight 0.1; approximation calculated from 12 points)
• TIN model (conforming the Delaunay triangulation rules)
DEM creation - ArcMAP
DEM creation - Surfer
Created models:
• Inverse Distance (cell size 2 m x 2 m, default settings of interpolation)
• Kriging with custom settings (cell size 2 m x 2 m, Search Ellipse Radius 1 a 2 = 40; Minimum number of data in all sectors = 5, Number of Search Sectors = 5)
• Kriging with default settings (cell size 2 m x 2 m, Search Ellipse Radius 1 a 2 = 150; Minimum number of data in all sectors = 4)
• Minimum curvature (cell size 2 m x 2 m, weight of tension 0,1)
DEM creation - Surfer
Created models:
• Natural Neighbor (raster model, cell size 2 m x 2 m, default settings of interpolation)
• Nearest Neighbor (raster model, cell size 2 m x 2 m, default settings of interpolation)
• Triangulation with Linear Interpolation (raster model, cell size 2 m x 2 m, default settings of interpolation)

Water volume calculations in ArcGIS
ArcGIS
• Raster models
Creation of water depth map
Calculation of water volume:
• Tin model:
„Surface volume“ tool
Surfer
• Water reservoir volume - calculated with „Volume“ tool
