Common use of Hydrology Clause in Contracts

Hydrology. Hydrology is the primary driver of successful wetland restoration or construction. In wetland restoration, hydrology needs to be re-established, whereas in wetland construction a reliable water source is required to establish hydrology. Include the following information on hydrology in the Proposal: • map(s) or figure(s) depicting the catchment area and drainage pathways of the replacement wetland; • the water source and discharge point for the replacement wetland, including any proposed shallow groundwater and/or surface water connections to existing waterbodies; and • classifications of the water regimes in the normative state (prior to anthropogenic disturbance), current state, and post-replacement state. The water regime refers to the surface water permanence in the deepest part of the wetland in most years, and can be classified as follows (adapted from ▇▇▇▇▇▇▇▇, et al2): o not flooded (less than 1 week flooded); o temporarily flooded (1 – 4 weeks flooded); o seasonally flooded (5 – 17 weeks flooded);
