	Rainfall, PE, land use (and subsequent crop growth) along with soil type all act in combination to control potential recharge. The rainfall decreases from west to east, whilst the PE increases. Mitigated by land use and the distribution of soils, this means that recharge generally decreases eastwards. Distribution of long-term average potential recharge maps for England and Wales are presented and discussed in [[OR/14/018 Results #Historical simulation \| Historical simulation]], see for example, Figure 8.

	Rainfall, PE, land use (and subsequent crop growth) along with soil type all act in combination to control potential recharge. The rainfall decreases from west to east, whilst the PE increases. Mitigated by land use and the distribution of soils, this means that recharge generally decreases eastwards. Distribution of long-term average potential recharge maps for England and Wales are presented and discussed in [[OR/14/018 Results #Historical simulation \| Historical simulation]], see for example, Figure 8.
