Effects of catchment management on physical river condition, chemistry, hydrogeomorphology and ecosystem service provision in small coastal rivers of the Western Cape

Petersen, Chantel R. (University of the Western Cape, 2019)

River systems are by nature complex and dynamic systems, which vary in structure and therefore function, and are closely connected to their landscapes. The primary aim of this thesis was to develop a systems operational ...

Application of enviromental and hydrochemical analysis to characterize flow dynamics in the Sakumo Wetland, Ghana

Laar, Cynthia (University of the Western Cape, 2018)
