Palioderli-Dam

This repository is the water deposit analysis of the Palioderli dam at Skopia (Greece)

Introduction

Skopia (Greece) is a small village in Municipality of Farsala, more here. In 2021 was announced a big project of creating a water dam in the local area of Palioderli.

Requirements

Docker
GDAL
QGIS

Input Data

DEM 4.77 meters resolution
Position of the dam

Processing

Download the DEM

docker run --rm -v ${PWD}/data:/data -t interline/planetutils:latest elevation_tile_download --outpath=data/elevation --bbox=22.37298,39.10379,22.52401,39.21161 --zoom=14

Merge the tiles into 1 GeoTiff file

docker run --rm -v ${PWD}/data:/data -t interline/planetutils:latest  elevation_tile_merge palioderli-dem.tif data/

Calculate the raster where the elevation is less than 412 meters (336 meters dam position initial elevation + 76 meters dam height)

Polygonize the result

gdal_polygonize.bat ./data/raster/water-deposit.tif -b 1 -f "ESRI Shapefile" ./data/vector/water-deposit.shp water-deposit DN

Calculate the DEM after filling the dam, in QGIS -> Raster Calculator

if("palioderli-dem@1" < 350.50, 350.50, "palioderli-dem@1")

Analysis

The dam will be constructed @ Χ = 0372321, Y = 4336653 (EPSG:2100) and water deposit height will be 350.50 m.
