Climate-proofing cities

Here's just one example, from Singapore:

Singapore's Marina Barrage.RnD.de.PortraitsSingapore's Marina Barrage.

The Marina Barrage and Reservoir, which opened in 2008, is at the heart of Singapore's two-billion-dollar campaign to improve drainage infrastructure, reduce the size of flood-prone areas, and enhance the quality of city life. It has nine operable crest gates,

Singapore – Catching Every Drop of Rain

Singapore - Catching Every Drop of Rain

The source of the map of the rivers of Singapore is the Singapore PUB

As a small island that doesn't have natural aquifers and lakes and with little land to collect rainwater, Singapore needs to maximize whatever it can harvest.

Currently, Singapore uses … Read the rest

Cutoff Divider in the SWMM 5 Kinematic Wave Solution

Subject: Cutoff Divider in the SWMM 5 Kinematic Wave Solution

A divider node in the SWMM 5 Kinematic Wave solution will divide the inflow to a node for two downstream links based on three criteria:

1. Cutoff Divider,
2. Tabular Divider, and
3. Weir Divider

The rule for a Cutoff
