Abstract

The Kaligesing area is part of the western part of the West Progo Dome. As the hard water area, water resources should be important problem to support rural development. The characteristics of the drainage as an indicator of water resources potential need to be understood in order to assess water potential. This paper wants to describe drainage characteristics as one of potential water resources indicators. The sufficient water resource is important for rural development. Result of the research shows that geological conditions allow this area to have relatively little water potential, but surface water can develop through rock-controlled flow patterns and geological structures. The flow characteristics in the area show rectangular, sub dendritic, and trellis patterns. Rivers develop genetically with consequent and subsequent types. Based on the quantity of water, the rivers in the study area include the intermittent and ephemeral rivers. Meanwhile, based on tectonics these rivers can be classified as superimposed rivers, where geological structures facilitate the formation of rivers in the research area. The river order in the study area shows the order of 1 - 4. Meanwhile, the density of the river is 0.81 - 1.86 km/km2 with young to mature river stages.

Highlights

  • This research was conducted in part of West Progo Hills, known as a hard water area

  • The geology of the study area is mostly composed of Tertiary rocks which are part of the West Progo Hills stratigraphy

  • The geological structure in the study area is strongly influenced by the processes that occur in the Oligocene-Miocene Period

Summary

Introduction

This research was conducted in part of West Progo Hills, known as a hard water area. Community life and land use, including agriculture and plantations, require water resources. The study of surface water is an important part of the research area. Goal of the research is knowing the characteristics of the drainage as an indicator of water resources potential. By knowing the drainage characteristics, it is expected that the potential of water resources can be assessed. The drainage patterns characteristics, both of the form and textures of channels and tributaries depend on local topography and subsurface geology [1, 2]. By studying geology we can understand the potential of water resources which are very much needed in the life of rural communities
