Abstract

Model for the Volume-Area-Depth Relations of Midfield Ponds using LiDAR

Highlights

Midfield ponds are numerous depressions observed on areas covered by ice during the last glaciation
The water balance of such areas is mainly influenced by the meteorological conditions, including precipitation, snow cover distribution, evapotranspiration and water evaporation, runoff and groundwater exchange
In order to evaluate the goodness of fit between the data points for both resolutions, root mean squared error (RMS) for volume Verr and area Aerr is defined by: VVeeeeee

Summary

Introduction

Midfield ponds are numerous depressions observed on areas covered by ice during the last glaciation Millions of such small depressional wetlands exist on the undulating terrain in Poland, and in the northern part of Europe and North America (Drwal, Lange 1985, Büllow-Olsen 1988, Lutze et al 2006, Sibbett 1999). Most midfield ponds are located in closed catchments without integrated drainage network Such wetlands are usually small and shallow, with the depth of about one meter or lesser (Fiedler Zhang et al 2009). Their size mainly depends on the size of melted dead ice bodies left by glacier (Drwal, Lange 1985), and they are often underlain by glacial till of very low permeability (Fiedler 2011, Winter, Rosenberry 1995). In summer, a significant water loss is open water evaporation (Winter, Rosenberry 1995, Johnson et al 2010, Fiedler 2011)
