Research note: Mapping spatial patterns in sewer age, material, and proximity to surface waterways to infer sewer leakage hotspots
Kristina G. Hopkins, Daniel J. Bain
2018, Landscape and Urban Planning (170) 320-324
Identifying areas where deteriorating sewer infrastructure is in close proximity to surface waterways is needed to map likely connections between sewers and streams. We present a method to estimate sewer installation year and deterioration status using historical maps of the sewer network, parcel-scale property assessment data, and pipe material. Areas...
Coherence between coastal and river flooding along the California coast
Kingsley O. Odigie, Jonathan A. Warrick
2018, Journal of Coastal Research (34) 308-317
Water levels around river mouths are intrinsically determined by sea level and river discharge. If storm-associated coastal water-level anomalies coincide with extreme river discharge, landscapes near river mouths will be flooded by the hydrodynamic interactions of these two water masses. Unfortunately, the temporal relationships between ocean and river water masses...
