|Abstract: ||The study determined and analysed morphometric characteristics of the Sumanpa catchment in the Forest-
Savannah Transitional zone of the Ashanti Region of Ghana. Quantitative morphometric parameters were determined
using remote sensing and GIS techniques to assess the requirements for ecological and hydrological conservation,
planning, development and management of the catchment landscape. Results indicated that the total length of stream
segments was highest under the first order streams and decreased as the stream order increased. The catchment has an area
of 38 km2with channel closeness of 0.934 km km-2 indicating permeable sub-soil. The catchment has a relief of 137m and
a total length of stream network of 36.51km out of which 61% was ephemeral, 38.9 % was second and third order streams.
The catchment has 44 % of its area located on slopes between 5-10o with generally good vegetation cover. There are 31
streams linked to a 3rd order trunk stream forming a trellis drainage pattern. The catchment’s morphometric features
suggest a general fragile topographic condition which needs strategic approach for soil and water conservation measures
and urban landuse planning.|
