Abstract

This dataset shows the recharge rates of the Nanaimo Lowland aquifer, British Columbia. The study area is from Nanoose Bay to Deep Bay, designating a low relief coastal strip along the southeastern part of Vancouver Island, BC. The average recharge rates were simulated by the 3D groundwater flow model. The recharge rates vary between 0 and 434 mm/y. The study area southeast and northwest extremities are the areas showing the highest recharge rates. The Englishman River sector is the one with the lowest recharge rates.

Introduction
Recharge raster creation
Process step Sources
The original recharge shapefile showed cells with recharge value of 0 mm/yr surrounded by uniform recharge value. The values of these cells were changed for the uniform value of the surrounding cells. To do thus, the cells were manually selected and the recharge value was changed by using « Field Calculator ». The recharge shapefile was then converted to a raster. The recharge values were modified from decimal numbers to whole numbers. To do thus, a new numeric without decimal field was added to the attribute table. The recharge values were added though ""Field Calculator"", requesting that the recharge values equal the original ones. The shapefile was then converted to a raster using the ""polygon to raster"" tool with a cell assignement type of Maximum_Area and a cellule size of 70.
