1 Evolution of the Po Delta, Italy Albert Kettner & James Syvitski, Charles Vörösmarty Dynamics and Vulnerability of River Delta Systems workshop September, 2007
2 Outline 21,000 years ago Effects of the ever changing natural driving forces on the Po River; long term simulations 1,000 B.C. 1,600 A.D. Coast line progradation (natural and controlled by humans) The effect of man-made reservoirs Subsidence of the Po Delta The different land uses of Po Delta Summary, Future study 2/17
3 Po characteristics a) Watershed ~75,000 km 2 b) Alps 4500m, Apennines 2000 m c) 15.5 million inhabitants d) One of EU S most agriculturally productive areas; irrigated e) 30% of total discharge is filtered by 5 lakes. f) Qmean = ~1525 m 3 /s, Qpeak = ~10,000 m 3 /s g) Qs = ~12 MT/yr, range = 2.9 to ~22.4 MT/yr Aqua modis 3/17
4 Evolution of the Po drainage basin; natural influences Kettner & Syvitski, in press LGM versus present day: 120m lower sea level 2.6 times larger drainage area Alpine ice sheet sediment flux increases According to climate models: 2.4 C colder and 18% less precipitation 4/17
5 Simulated Water and Sediment flux since the LGM HydroTrend: Climate-driven hydrological transport model that uses basin properties as well as biophysical parameters to simulate water and sediment fluxes at the river mouth Results: Decrease in water discharge by a factor of 1.9 Decrease of Sediment load by a factor 3.5 Kettner & Syvitski, in press 5/17
6 Historical coastline before human control Before human control Natural rate of coastal progradation 4 m/y from 1000 B.C. to 1200A.D. Seven points of discharge described by Pliny the Elder 6/17
7 Human interference that forms the modern delta abandonment of Po di Primaro 1152 AD a major natural avulsion northward shifting of distributary channels Venice Republic is threatened by the potential infilling of the lagoon 1604 AD digging of a diversionary canal (Taglio di porto Viro) 7/17
8 Effect of human impact on sediment flux Resulting in: Morphological evolution Deforestation & Mining Pastures to Cropland Dams & Diversions Calendar Years Simeoni et al., 2006 Syvitski & Kettner, /17
9 Model simulations of the effect of reservoirs HydroTrend simulates the trapping efficiency of reservoirs based which is a function of the volume of the reservoir and its receiving discharge (Brune equation). HydroTrend simulation of the Pescara River (Apennines) pre and post dams Sediment load (Mt yr -1 ) 9/17
10 Subsidence of the Po Delta C Natural subsidence 1990s Simeoni et al., /17
11 Present elevation of the Po Delta and the coastal lowlands Elevation (m) < >100 SRTM data km 12/17
12 Distributary Channel Flood Control: Sediment Storage MT 4 Between Ariano and Goro MT/mo Between Goro station and Goro Mouth MT/mo Po Discharge m 3 /s Ariano Goro Stop-bank levees cause superelevation of the channels above the surrounding floodplain. Goro mouth 13/17
13 Flood risk map the Po Delta Autorita' di Bacino del fiume Po, Progetto di Piano stralcio per l'assetto Idrogeologico del Delta (PAI-Delta), /17
14 Land uses of the Po Delta agricolture houses tourism energy aquaculture Valli da pesca Slide of Sara ARIANO Sacche (clams, mussels) 15/17
15 Summary: Natural Po Delta system is controlled by sea-level rise and sediment flux reduction (21ky ) Humans Delta progradation accellerates caused by confining the Po discharge to a small area. (10 Century ) The present delta is artificially held in position within context of the northern Adriatic oceanographic processes Natural and artificial subsidence are enhanced by levee construction, which prevents overbank sedimentation River-bed excavation and river damming in the drainage basin during the last 50 years led to a marked decrease in sediment supply 16/17
16 Future goals in modeling sediment fluxes Summary: HydroTrend simulations of water and sediment flux at the outlet Future: Creating a spatially distributed model that determines erosional as well as depositional areas (such as a delta) within a drainage basin that could be used as a decision model for managers (NASA project ) 17/17
