Diamond Point is really a cuspate foreland on the northwestern entrance to Discovery Bay. For most decades – greater than a century ago – there is a federal quarantine station and hospital on this website. It had been eventually closed plus the land sold. In the late 1950s, a residential development was built round the spit and a little private airstrip and little now remains from the historic buildings aside from the old wharf. Like the majority of of the features, as the overall shape is rather symmetric, the facts aren’t. The north limb is more drift-aligned, the south limb is more swash aligned. The north limb suggests long-term erosion, the south limb appears a lot more stable. That is probably one reason that north side is heavily fortified, as the south side isn’t. The north side is influenced (occasionally) by longer period swell and contains a more substantial fetch for storm waves. The south side probably experiences more frequent storm waves, however the energy is bound with the fetch the bay.

Sediment transport is east across the northern shore, towards the idea. Sediment transport is really a bit less clear in the south side. Keuler’s USGS map shows that drift continues round the point from north and continues southward across the northwestern shore on the bay. An alternative solution explanation will be that Diamond Point represents the convergence of drift from both north and south. This involves that southerly waves action dominates across the bluffs south of Diamond Point and that the erosion of these bluffs feeds the Point’s southern beach. I’m inclined to trust the latter, but would want more to put into practice than what I’ve at hand. There is at the very least some evidence that waves may wrap round the point from north carrying sediment using them (accretion close to the tip in the southern side), but I’m uncertain it gets much farther. Residents for the south side are worried about erosion and overtopping in the past couple of years and we discussed several possible explanations. 1. Chronic erosion from the south beach. I saw little to suggest this is the truth, in the field, in older aerial photos, or inside the community’s historic photos.

Old boat ramps didn’t indicate much longterm beach change (ramps could be good references for noting beach profile changes). And for a few of the reason why above, I’d expect this beach for being relatively stable – maybe even accretional (although there wasn’t much proof that, either). 2. History. Erosion problems frequently have a human element. Boat ramps and groins can transform sediment transport and cause localized erosion (and/or accretion). When they are present for most decades, then decay, the beach gradually reverts to a far more natural configuration, although at that time the specific culprit has vanished, leaving everyone scratching their heads in the “unexplained” erosion. In cases like this, you can find boat ramps nearby, but there is no obvious indication they were affecting the bigger reach. A far more likely issue, at the very least in my own mind, was the old wharf. When active, it could have sheltered the beach from wave action and allowed accretion that occurs. But then since it fell apart, the beach could have eroded since it tried to reclaim its former position. If it has happened, there is no obvious proof it.
Like generally in most flood zones, flood events are infrequent and vary in frequency.
The logs are a fascinating story. The historic photos, along with the memories of old timers, indicate huge amounts of logs with this beach (and several other beaches) many decades ago, but with numbers gradually diminishing since. That is consistent with an over-all notion that there have been huge amounts of logs in the machine mid-20th century, but they have been gradually lost since that time – for most reasons. For the extent that broad rafts of logs protect the beach, their loss may lead to erosion. 3. Short-term erosion linked to storm events. That is common on beaches such as this, particularly after extreme events like last December’s record high tide. Logs get floated away, exposing the actual gravel to localized erosion and redeposition, but this won’t necessarily reflect a far more serious pattern. The larger problem is normally the overtopping itself, but that’s more a flood issue than an erosion one (and suggests different solutions). This can be a barrier beach (or what Wolf Bauer named an accretion beach). They are flood zones. The berm was built by storm waves and there is absolutely no reason to believe that this storm waves won’t reach it again. Like generally in most flood zones, flood events are infrequent and vary in frequency. Severe events will most likely look like an indicator of things getting worse, due to the fact few people will recall the final time it just happened. That is also a tsunami hazard zone, fortunately those are particularly infrequent.
It is hoped that preparation helped individuals to mitigate their losses at the very least some.

It really is good to truly have a intend to also save our mementos and writing whenever we have the ability to survive. Many thanks a great deal for leaving a comment. Cyndi, I’m not concerned about the storms, I understand that it could be the most amazing day and I could be relaxing in a lounge outside or anywhere, when my time on the planet is up, I’m gone. I many thanks for your useful ideas. We’ve plenty of tornado threats in your community through the spring. Nothing beats the midwest, but enough to cause you to think about having some things together and set up.
