ABSTRACT
Sedimentary processes are largely controlled by just two agencies, water and wind. Thus the hydrological and wind cycles play very important roles in sedimentation. The hydrological cycle is schematically represented in Fig. 2.1. Schematic representation of the hydrological cycle. The balance between evaporation and precipitation in an ideal tropical region is indicated by arrows. The figures within the circles (modified after <xref ref-type="bibr" rid="ref_366">Siever 1983</xref>) give an approximate idea of the proportion of water flow per year. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203749883/d9482c17-0110-46b7-8328-bb149a458cd9/content/fig2_1.tif"/>
