| These floodplains offer important ecological, hydrological and recreational functions and values. |
| However, their concentration is governed by the hydrological regime of the river systems. |
| This shows that Mars, like the Earth, once had an active hydrological cycle that ultimately led to running water on its surface. |
| The climate itself is strongly determined by the carbon oxygen cycle and the hydrological cycle. |
| The timing and extent of any changes in salt-affected areas will depend on the net changes in the hydrological cycle in each catchment area. |
| The hydrological characteristics of the lake are important for how meteorological conditions in winter affect biological processes. |
